Car sounds wweful when starting up cold

red6spd

Its a warm up cycle. I can't explain exactly what happens during the process but the car is trying to heat the catalytic converters quickly so the car produces clean emissions. When the "cats" on the car are cold they are not doing their job properly so by getting them warm as fast as possibly Nissan makes the tree huggers happy. I giggle each time cause I have no "cats" on the car and I'm like "what are you trying to warm up little Z?" LOL!!!

The lack of throttle response is probably due to the strong survival instinct built into the engine control system. There is at least one thread on this site about adjusting the throttle control for snappier response.
